🔍 Key Concepts

• High-velocity fog vs. low-velocity fog in marine firefighting • How water fog actually puts out fires (cooling, smothering, or both) • Typical pressure and reach characteristics of high-velocity fog nozzles

💭 Think About

• Think about what makes high-velocity fog different from low-velocity fog in terms of droplet size and spray pattern. • Ask yourself: does high-velocity fog mainly work by cooling, by cutting off oxygen, or by doing both at the same time? • Consider whether high-velocity fog usually has a short reach and low pressure, or a longer reach with higher pressure compared to low-velocity fog.

✅ Before You Answer

• Check which choice correctly describes the extinguishing action of water fog on a fire. • Verify whether high-velocity fog normally uses higher or lower pressure than 60 psi. • Confirm if high-velocity fog is actually finer and more diffuse than low-velocity fog, or the opposite.

Question 1 of 20

Which is TRUE of High-velocity fog?

It produces an effective fog pattern no more than 6 feet beyond the nozzle

It requires that the water pressure be no greater than 60 psi

It extinguishes a fire by absorbing heat and reducing the supply of oxygen

It is a finer, more diffuse water spray than low-velocity fog
